Development of Conical Metallic Bladders for Transpiration Cooled Nosetips.
Abstract
The objective of this program is to develop a conical metallic bladder with at least 98% expulsion efficiency which could withstand anticipated operational reentry environments. The program was divided into three phases; Phase I design; Phase II fabrication and testing of various expelling, half bladder configurations, and Phase III fabrication and testing of the selected design configuration under dynamic flight environments. During Phase I existing conical metallic bladder designs, developed under a previous independent research and development program, were analyzed and design changes made to provide controlled bladder collapse through the use of (1) area bonding, for shell stabilization, (2) gas flow control holes, for desired initiation response and expulsion mode control and (3) release tape, for critical area release and start transient response control. The Phase II activity was focused upon the experimental evaluation of the approaches selected to control the bladder collaspe mode. Half bladder testing was conducted to determine the design approach and configuration which best produced the desired results. (Author)
